I can't edit a page using the imagemap tag when logged in. This is for a mediawiki installation where all editors must be logged in.
If I change the permissions and allow all users to edit, then I can save the page. But if I change permissions back to $wgGroupPermissions['*']['edit'] = false; then login and try to edit the page, I get a blank screen after hitting "Save Page".
I tried to ask on the mediawiki help site but was unable to post.
